Definitions

  • the invention relates to a one-piece pushbutton arrangement with at least two adjacent pushbuttons, struts and connecting webs, which largely ensures that when a pushbutton is operated, adjacent keys move only very little.
  • a female connector describes, for example, the German patent DE 3034585, which discloses a profile strip made of clip brackets for receiving the push buttons and curved, preferably V-shaped connecting webs at intervals of two clip brackets.
  • the push buttons are attached to the clamp bracket and the flexible connecting webs ensure that the push buttons can be depressed without difficulty.
  • the springs spring back after being pressed down is also ensured by separate frog springs.
  • a telephone keypad with multi-row control keys integrated in a female connector is described in European Plastics News, No. 10, 1983, page 63.
  • This key block is produced by molding part of the keys in a first injection molding step and completing the keys in a second injection molding step and providing them with a frame connecting the keys.
  • US 5270507 discloses a push button arrangement in which adjacent ones
  • Pushbuttons are connected to each other by bars.
  • the webs are designed at their ends facing the pushbuttons as spring struts, so that the pushbuttons are movably mounted over the resilient parts of the webs and the entire pushbutton arrangement can rest on a base on the sections of the webs lying between the spring struts.
  • the entire push button arrangement is made of a rubber. The thickness of the webs is essentially constant over their entire length.
  • a disadvantage of the push button arrangement already described is that the spring action of the struts is directly related to the strength of the connecting webs. When the spring action is increased, the coupling of the pushbuttons to one another is also always increased.
  • the object of the present invention is to eliminate the disadvantages of the prior art by simple design measures.
  • This object is achieved by a pushbutton arrangement with at least two adjacent pushbuttons which are connected to one another by connecting webs, characterized in that each of the pushbuttons (2) has two spring struts (4) which are supported on a support surface.
  • the present arrangement of struts and connecting webs creates two mutually independent functional elements which can be appropriately designed with regard to their actual task and function without this having an adverse effect on the function between the two components.
  • the functional reliability of the key arrangement is therefore considerably improved.
  • the restoring force exerted by the struts on the push button can therefore be effected independently of the connecting webs.
  • the connecting webs can thus be freely dimensioned in the push button arrangement according to the invention, since the spring action is independent of the thickness of the connecting webs and depends on the nature of the struts. Another advantage is that the mechanical decoupling of adjacent push buttons is possible, so that when a push button is operated, adjacent buttons do not move and no unwanted contact or switching effect of an adjacent button is triggered.
  • the spring struts on each pushbutton are arranged laterally offset from one another; the pushbuttons preferably have a base on which the spring struts are provided.
  • the spring struts are preferably of flat profile and are supported with their free end on the contact surface.
  • the free end of the spring struts preferably has a section which is offset parallel to the support surface and which is supported on the support surface.
  • the struts can also extend from the bottom of the push buttons (2) under the push button arrangement.
  • the connecting webs are flexible.
  • the connecting webs particularly advantageously have a taper, which is provided either on the upper side facing the pushbuttons, on the lower side or on the side surfaces of the connecting webs.
  • the taper is preferably provided in the middle of the connecting web between the push buttons.
  • the taper is particularly preferably designed as a film hinge, and the connecting webs are very particularly preferably in the form of tapered film hinges.
  • the push button arrangement according to the invention is particularly advantageously produced from a particularly rigid polyacetal polymer with a high restoring force.
  • the connecting webs can be tapered down to 0.2 mm without fear of breaking the connecting webs if the buttons at the tapering points are used continuously.
  • the use of an easy-flowing polyacetal also makes it possible for the push button unit to be integrated in one, despite the tapering which hinders the flow of the plastic
  • Suitable polyacetal homopolymers and copolymers generally have a melt index (MVR) of at least 12.
  • Suitable copolymers have a comonomer content of generally less than 3.4% by weight, based on the monomer trioxane, preferably less than 2% by weight, in particular 1.4% by weight.
  • the connecting webs are designed to be flexible in that the connecting webs consist of an elastomer preparation (crosslinked or uncrosslinked), preferably a thermoplastic elastomer preparation, which has good adhesion to the material of the push buttons.
  • the pushbuttons preferably consist of a polyacetal and the connecting webs consist of a thermoplastic elastomer preparation as described, for example, in WO 00/20204, US 5149589, US 5002625 or US 5472782, to which reference is made.
  • Such a push button arrangement is preferably produced by two-component injection molding.
  • FIG. 1 shows a section of a single-row push button arrangement 1 of push buttons 2, which are connected to one another via connecting webs 3.
  • the spring struts 4 serve to rest the pushbutton arrangement 1 on a support surface (not shown) or a frame and to reset the pushbutton after it has been depressed.
  • the connecting webs 3 have a taper in their center. This taper is shown in the illustration on the top of the connecting webs facing the pushbuttons, but it can also be carried out on the bottom or from both sides.
  • the single row push button arrangement 1 can be connected to other push button rows or a frame.
  • FEM calculations can be used to show, for example, that at a deformation (depression) of a push button by 1.25 mm, the adjacent push buttons are also moved by only 0.35 mm. If the entire length of the web is 0.8 mm, the adjacent push buttons are moved by 0.63 mm with the same deformation of a push button.
  • the material properties of ⁇ Hostaform C 13031 (Ticona GmbH) were also taken into account in the calculations.
  • FIG. 2 shows a section of a two-dimensional pushbutton arrangement 5 of pushbuttons 6, which are connected to one another via connecting webs 7, the pushbuttons 6 being movably mounted via the spring struts 8.
  • the push button arrangement according to the invention can be designed as a pair, group, row or two-dimensional key arrangement as required.
  • Such a push button arrangement is used, for example, in control panels of household appliances, in particular so-called white appliances such as washing machines, refrigerators, tumble dryers, kitchen stoves etc., as keyboards for calculating machines, typewriters, computers and telephones, in particular mobile telephones, notebooks etc., control panels for radio and music , Video and TV devices, control panels for machines and machine tools or elevators, control and control panels in vehicles etc.
  • the push button arrangement according to the invention can be used advantageously in particular where closely spaced control buttons have to be accommodated in a space-saving manner in a device or component and at the same time it has to be ensured that when a button is pressed, no adjacent buttons are moved with it and thus possibly. trigger a signal.

Abstract

La présente invention concerne un dispositif de boutons-poussoirs constitué d'au moins deux boutons-poussoirs voisins, de brides de liaison et de jambes d'amortissement. Dans ledit dispositif, les brides de liaison se présentent sous la forme de charnières minces effilées, la longueur des brides de liaison valant de préférence de 3 à 10 mm, la largeur des brides de liaison valant de 0,5 à 2 mm, et l'épaisseur des brides de liaison valant de 0,5 à 1,5 mm à leurs extrémités et de 0,15 à 1 mm dans leur partie centrale effilée, mais étant dans tous les cas plus petite dans leur partie centrale effilée qu'à leurs extrémités. Le dispositif de boutons-poussoirs est de préférence formé en une seule pièce à partir de polyacétal à écoulement libre qui présente des rigidité et résilience élevées.
